Abstract
A preparative scale method for the isolation of unreduced oligosaccharides of glycoproteins and glycohormones having a N-linked oligosaccharide structure is disclosed. The method employs hydrazinolysis of the glycoprotein or glycohormone under reaction conditions to cause cleavage at the N-linked sites, producing a mixture having as a major component a de-N-acetylated hydrazone derivative of the oligosaccharides, followed by N-acylation of the hydrazone derivative, acid-catalysis of the hydrazone derivative to produce unreduced oligosaccharides, and subjecting the resulting unreduced oligosaccharides to cellulose column chromatography to remove contaminants and to recover the unreduced oligosaccharides.
